форму для выбора основного изображения с помощью радиокнопки php

Question

Я пытаюсь найти лучший способ обработки формы, которая будет использоваться для выбора основного спонсора (аналогично выбору основного изображения из коллекции) и обновления базы данных , заменив значения.

Это форма я пытаюсь использовать, чтобы сделать изменение

       </tr></table>    
      <button id="newpartner" type="submit" name="save_partner_btn">Save Main Sponsor</button> 
     </form> 

PHP часть

else if (isset($_POST['save_partner_btn'])) { 
    $partner = (isset($_POST['partner']) ? $_POST['partner'] : null); 
    $sponsor = $_POST['sponsor']; 

    echo $partner ."<br>"; 
    echo $sponsor; 
} 

В настоящее время вопрос заключается в том, что независимо от того, какая кнопка радио выбрана, не вторит Значение равно «41» (то же, что и последнее значение). Как я могу это исправить?

Answer 1

Используйте этот

<form action="" method="POST"> 
    <input type='hidden' name='partner' id='partner' value=''/> 
     <table id='partnertable'> 
      <tr id='head'> 
       <th class='col4'>Logo</th> 
       <th class='col1'>Partner</th> 
       <th class='col2'>URL</th> 
       <th class='col3'>Actions</th> 
       <th class ='col4'>Main Sponsor</th> 

      </tr><tr class='details'> 
       <td class = 'col4'><img id='logos' src='../media/images/logo1.png'/></td> 
       <td class='col1'>Pure</td> 
       <td class='col2'>http://www.pureconcepts.com.mt/</td> 
       <td class='col3'><a href='delete.php?partnerID=21'>Delete</a>|<a href='logo.php?logoID=21'>Edit</a></td>     
       <td class='col4'><input type= 'radio' name='sponsor' value='4' onclick="addHiddenValue('21');"/> 
      </tr><tr class='details'> 

       <td class='col4'><img id='logos' src='../media/images/logo2.png'/></td> 
       <td class='col1'>wuerth</td> 
       <td class='col2'>http://www.wuerth.com.mt/</td> 
       <td class='col3'><a href='delete.php?partnerID=22'>Delete</a>|<a href='logo.php?logoID=22'>Edit</a></td> 
       <td class='col4'><input type= 'radio' name='sponsor' value='4' onclick="addHiddenValue('22')"/>  
      ----- 
      ----- 
      ---- 

А Javascript

function addHiddenValue(val){ 
    document.getElementById("partner").value = val; 
} 

и обновить его значение в JavaScript или JQuery, когда они выбирают радиокнопку

Answer 2

В зависимости от реализации, это может работать:

<form action="" method="POST">     
      <input type='hidden' name='sponsor' value='4'> 
      <table id='partnertable'> 
       <tr id='head'> 
        <th class='col4'>Logo</th> 
        <th class='col1'>Partner</th> 
        <th class='col2'>URL</th> 
        <th class='col3'>Actions</th> 
        <th class='col4'>Main Sponsor</th> 

       </tr><tr class='details'> 

        <td class='col4'><img id='logos' src='../media/images/logo1.png'/></td> 
        <td class='col1'>Pure</td> 
        <td class='col2'>http://www.pureconcepts.com.mt/</td> 
        <td class='col3'><a href='delete.php?partnerID=21'>Delete</a>|<a href='logo.php?logoID=21'>Edit</a></td> 
        <td class='col4'><input type= 'radio' name='partner' value='21'/></td> 
       </tr><tr class='details'> 

        <td class='col4'><img id='logos' src='../media/images/logo2.png'/></td> 
        <td class='col1'>wuerth</td> 
        <td class='col2'>http://www.wuerth.com.mt/</td> 
        <td class='col3'><a href='delete.php?partnerID=22'>Delete</a>|<a href='logo.php?logoID=22'>Edit</a></td> 
        <td class='col4'><input type= 'radio' name='partner' value='22'/></td> 
       </tr><tr class='details'> 

        <td class='col4'><img id='logos' src='../media/images/logo3.png'/></td> 
        <td class='col1'>magri cycles</td> 
        <td class='col2'>http://www.magricycles.com/</td> 
        <td class='col3'><a href='delete.php?partnerID=23'>Delete</a>|<a href='logo.php?logoID=23'>Edit</a></td>
